Detailed ways

The technical solutions of the present invention will be more clearly and completely described below through the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in FIG. 1 , the robot anti-collision buffer assembly of the preferred embodiment of the present invention includes a guardrail plate 1 and a plurality of buffer members 2. One end of the buffer member 2 is connected to the guardrail plate 1, and the other end of the buffer member 2 is connected to the robot. , the robot is impacted on the guardrail 1 by force, and is buffered by the buffer 2.

The buffer part 2 includes a shaft sleeve 3 and a connecting rod 4. Inside the shaft sleeve 3 are a sliding plate 5, a slip ring 6, two small springs 7 and large springs 8 with different elastic coefficients.

The connecting rod 4 is fixedly connected to the sliding plate 5 , and the connecting rod 4 is connected to the guardrail board 1 . The sliding plate 5 can slide along the axis of the shaft sleeve 3, and a first chute 9 is provided inside the shaft sleeve 3 for the sliding plate 5 to slide. Compress the small spring 7. The slip ring 6 is also inside the sleeve 3, and the slip ring 6 can also slide along the axis of the sleeve 3. The inside of the sleeve 3 is provided with a second chute 10 for sliding the slip ring 6, a first chute 9 is longer than the second chute 10. The sliding sleeve must slide along the shaft sleeve 3 for a certain distance before it can come into contact with the slip ring 6 . One end of the large spring 8 is in contact with the slip ring 6 , and the movement of the slip ring 6 will compress the large spring 8 .

Buffering process:

When the guardrail 1 is hit, the guardrail 1 moves the sliding plate 5 through the connecting rod 4 , and the sliding plate 5 compresses the small spring 7 , which realizes buffering. As the sliding plate 5 continues to slide, the lower surface of the sliding plate 5 contacts the upper surface of the slip ring 6 , the sliding plate 5 further moves the slip ring 6 , and the slip ring 6 moves and compresses the large spring 8 . Because the elastic coefficients of the large spring 8 and the small spring 7 are different, the ability of the large spring 8 and the small spring 7 to buffer the impact force is different. When the impact force is large, the ability to deal with the large impact force can be improved. Spring 7 compresses easier. Make the buffering effect adaptable according to the impact force.

The slip ring 6 is in the shape of a circular ring, and a rubber pad is adhered to the upper surface of the slip ring 6 . When the sliding plate 5 collides with the sliding ring 6, the rubber pad can weaken the sound generation.

The end of the shaft sleeve 3 away from the connecting rod 4 is provided with a screw plug 11. The peripheral wall of the screw plug 11 is threadedly connected to the inner wall of the shaft sleeve 3.
